Will the orange icon on an android phone still pop up even if I don't have messenger there's a number two in the orange box on the app but I don't have messenger installed is there messages there or what does it mean

The orange box that pops up on my phone that I get texts has an orange box and a preview of upcoming text in my messenger. I turned off everything everywhere that says preview or popup and xant stop it. Anyone have an idea what this is.

Welcome to the forums. That's a picture of your recent apps/multitasking overview, right? Long press that small icon (orange circle with the three dots inside) and then tap "i" (info). This will tell you which app pushed that screen.
